A rath, the Irish term for a ringfort, was typically a circular enclosure defined by an earthen bank and ditch, used as a farmstead during the early medieval period. The one that stood here on a south-facing slope in County Cork measured roughly thirty metres across. Today, levelled and leaving no visible surface trace, it survives only on paper.

The 1842 Ordnance Survey six-inch map recorded it clearly as a circular enclosure, and noted something else of interest on its north-eastern edge: a lime kiln. Lime kilns were small stone structures used to burn limestone and produce quicklime, primarily for spreading on agricultural land to reduce soil acidity. The presence of one so close to the ringfort's perimeter does not mean the two were contemporary; by the nineteenth century, farmers routinely built and used such kilns wherever suitable stone and fuel were available. But the proximity is suggestive of a long continuity of use, the same south-facing slope attracting settlement and agricultural activity across very different centuries. At some point between that 1842 survey and the present, the earthworks were levelled, most likely through agricultural improvement or repeated ploughing.
